The fully redesigned Google+ is being rolled out starting today, and it puts Communities and Collections front and center.

Now focused around interests, the new Google+ is much simpler. And it’s more mobile-friendly—we’ve rebuilt it across web, Android and iOS so that you’ll have a fast and consistent experience whether you are on a big screen or small one.

You’ll need to opt-in to this new version of Google+ on the web to see the changes.
